The three-wheeled RowRay by Troels Oehman (Danish spelling, Øhman) is designed to provide a form of exercise that incorporates the needs of busy families in the quest to get fit. Once family members are seated, they can get moving by using an arm motion similar to rowing to power the RowRay. Because the rowing motion uses a bar, not oars, it is very efficient and makes powering the machine possible for both children and adults.
Renting the vehicle using a cell phone app is also part of the plan. Just rent the RowRay by Troels Oehman and row to roll around recreational areas, suburban parks and residential streets.
